Hapkido is the "way of co-ordinated power". It is a Korean martial art that is often referred to as the complete martial art of self defence.
Hapkido is not a sport but rather a pure self-defence martial art that covers joint locks, sweeps & throws, striking techniques with all parts of the body, ground fighting, defence against weapons and the improvised use of everyday items in self-defence situations. Because Hapkido techniques work through Balance Point and Joint Manipulation principals, physical strength is not required so learning Hapkido is not restricted by age, size or gender. It is very much an art that grows with age.
